I have to agree with this. We need to face up to the reality that the things that make a "traditional" diesel engine attractive - (1) simple design, (2) ability to use cheap, less refined fuel, and (3) good fuel economy - simply don't apply to modern diesels.
You forgot (4) performance. The power curve and low end grunt of a Diesel engine lend themselves quite well to offroad applications. This is one area where modern diesels win the prize as modern injection systems and turbo charging have given these new engines some legs where the old ones would fall flat after the torque gave out.
All that said, I wouldn't buy a diesel tacoma. Not because of the engine, but because its a second rate light duty vehicle built to satisfy the bean counters. Start with a proper chassis, lose the tupperware bed, and then we'll talk.
